But on closer inspection, it's pretty obvious this isn't Bono. First of all, Bono doesn't do t-shirts. Plus, he celebrated his 53rd birthday last Friday and is busy recording U2's upcoming album, which is expected to be released by the end of the year.

We've reached out to SAP to see if they were behind this. But in a blog post earlier this week, SAP acknowledged that the Bono impersonator may have been hired by one of its partners.

Unfortunately for SAP, some tech pundits are drawing comparisons between the fake Bono and SAP's new HANA Enterprise Cloud service, which debuted last week. It's a cloud-based version of SAP's speedy in-memory database.

Matt Asay at Readwrite said Friday that HANA Enterprise Cloud isn't really a cloud at all, since customers need to have already purchased a regular software license in order to use it. In other words, it's as much of a cloud as the Bono impersonator is a rock star.
